Verdict

The call

The clearest difference is in-app purchases: Mainteco at none against Microsoft Outlook's 3. Mainteco also leads on ads (none vs shown) and iOS requirement (15.6 vs 26.0). Microsoft Outlook's advantage is chart position (#12 vs unranked) and update cadence (weekly vs fortnightly). On price and device support there is nothing between them.
